Composed in 1771 to a libretto by Metastasio tracing the well-known biblical story of Judith and Holofernes, La Betulia liberata was Mozart’s first oratorio. Often described as a stroke of genius, this recording by Les Talens Lyriques and Christophe Rousset, with Sandrine Piau, Amanda Forsythe and Teresa Iervolino, shows the dramatic intensity of which he was already capable at the age of just fifteen and the influence of his early experiences with opera.

This ninth volume of the Haydn2032 series focuses on the composers psychological subtlety in its focus on a central work: his Symphony no.45, known as the Abschieds-Symphonie (Farewell Symphony), composed in 1772. It is said to have got its nickname from a symbolic message Haydn conveyed to Prince Esterházy when he and his orchestra were required to stay longer than planned in the Princes summer residence. On the occasion of the symphonys first performance, Haydn had arranged for the musicians to leave their places one by one during the final Adagio.

Soprano Sandrine Piau has been known mostly as a Baroque specialist, but she has recorded several albums of 19th century French mélodies with spectacular results. Si j'ai aimé (the title comes from one of three songs by the little-known Théodore Dubois) will be very hard for her to outdo. The list of attractions is very long and begins with the repertory. There are some familiar pieces here, such as the opening pair of songs by Saint-Saëns, but many of the composers – Dubois, Charles Bordes, Alexandre Guilmant – are rarely performed, at least outside France, and all the songs here are top-notch.

Handel's opera recorded live at the Semperoper, Dresden, in June 2000. Equal parts comedy, tragedy and romance, the story revolves around the love both Xerses, King of the Persians, and his brother Arsamenes have for Romilda. Christophe Rousset conducts Les Talens Lyriques, with performances by Paula Rasmussen, Ann Hallenberg, Patricia Bardon, Isabel Bayrakdarian and Matteo Peirone.

Les fêtes de Paphos (The Festivals of Paphos) is an opéra-ballet in three acts (or entrées) by the French composer Jean-Joseph Cassanéa de Mondonville. The work was described as a ballet héroïque on the title page of the printed score. Each act had a different librettist. Les fêtes de Paphos was first performed at the Académie royale de musique, Paris on 9 May 1758 and was a popular success. Mondonville recycled material from two of his previous operas for the first two acts, namely Erigone (1747) and Vénus et Adonis (1752), both originally composed for Madame de Pompadour's Théâtre des Petits Cabinets. The title of the work is explained in the preface to the printed score. Paphos was a city in Cyprus sacred to Venus, the goddess of love. "Reunited on the island of Paphos, Venus, Bacchus and Cupid decide to enliven their leisure in such a pleasant location by celebrating their first loves, and this gives rise to the following three acts and the title Les fêtes de Paphos."

Until recently, so much of this first opera that Handel wrote for Italy was lost that it was unviable to stage it. The rediscovery of the missing material, a triumph of scholarly detective work, reveals the confident high spirits which characterise so much of Handel’s music during his Italian visit. It lacks the instrumental colours of his more lavish London productions, with many arias supported by continuo alone. All are here, complete (even six which Handel himself discarded), but many are brief and, under Curtis’s lively direction, the dramatic tension builds up splendidly.

Rescue operas are not what one is used to associating with Handel, yet that, in a sense, is what this is. Costanza, a princess of Navarre, has been shipwrecked on Cyprus, where she now awaits the arrival of her betrothed, Richard the Lionheart (yes, the same). The island's tyrannical ruler, Isacio, fancies her for himself, however, and spends the entire opera trying to prevent the intended union from going ahead, first by sending Riccardo his daughter Pulcheria instead, and, when that has failed thanks to Pulcheria's brave entreaties, by imprisoning Costanza and declaring war. Only with his final defeat by Riccardo's army, aided by Pulcheria's own fiancé Oronte, do things finally turn out happily.

Neapolitan music of the 18th century, so important in the formation of the musical lingua franca of the Classical period, is a massively neglected area wherein lie many riches. Despite his greater interest in opera, Leo was maestro di cappella at the Naples royal chapel and composed a good deal of church music, especially towards the end of his life (he died in 1744), in which sound counterpoint and the clarity of modern melodic developments are successfully combined. These are not sterile exercises in ‘old-style’ polyphony, but works of honest, thoroughly Italianate expression.

Recordings that include strings quartets by Schoenberg, Berg, and Webern are common, but an album that includes music for quartet and voice by each of them is a rarity. Schoenberg's Second String Quartet, with a part for soprano in its third and fourth movements, is standard repertoire, but the version of Berg's Lyric Suite with a vocal part in the final movement is highly unusual, and Webern's bagatelle with voice, an unpublished movement apparently once intended to be part of the Six Bagatelles, Op. 9, receives what is probably its first recording. Novelty aside, the high standards of these performances make this a formidable release. Founded just before the turn of the millennium, Quatuor Diotima plays with the assurance and mutual understanding of a seasoned ensemble. The quartet has a lean, clean sound and the ensemble is immaculate, playing with exquisite expressiveness, an ideal combination for this repertoire.

Soprano Sandrine Piau's new project is dedicated to French baroque repertoire, offering a wide range of very beautiful arias by Rameau, Lully, Campra etc in a 100-year journey that mixes very famous music with little-know pieces, such as arias by Grétry or Sacchini > Sandrine Piau and Jérôme Correas, a former singer, founder and music director of Les Paladins, have worked together on a regular basis since their early careers, especially with William Christie.

The services of Matins and Lauds in the Roman rite for the last three days of Holy Week, the so-called Sacred Triduum are – or were before being replaced by the vernacular liturgy – beautiful and complex. Matins for Maundy Thursday, Good Friday and Holy Saturday consist of psalms with antiphons, readings from the Lamentations of Jeremiah and versicles and responsories related to and reflecting upon the events of those days. Over the centuries they have proved fruitful inspiration for music, even in post-reformation England, where the Book of Common Prayer continued to prescribe readings from Lamentations and settings of them, often in Latin, continued to be sung in cathedrals and collegiate churches.

This beautifully played and recorded disc is a must for all Francophiles.

Anyone who enjoys Mozart opera should hear this disc. Yet quite a few people who'd probably love it to death if they listened are going to pass it by. Why? Well, look at the selections - it's not exactly a 'greatest hits' selection in the truly popular sense. Lucio Silla, Il re pastore, Mitridate, Zaïde - hardly front rank Mozart operas in the public consciousness; with Die Entführung we're getting closer - and suddenly you spot track 2, Pamina's gorgeous lament to lost love from The Magic Flute: 'Ach, ich fühl's' - anyone who hears Sandrine Piau singing this famous number will want to experience the rest of the recording no matter what.

Handel, Scarlatti, Corelli, Stradella, Muffat … From 1650 to the beginning of the eighteenth century, Rome exercised an immense power in attracting composers from all over Europe and experienced an intense moment of musical activity, because of - or in spite of - the papal administration. It was a prosperous period with a melting pot of influences. The programme devised here by the Roman conductor, Rinaldo Alessandrini, offers a complete and personal vision of the time, passionate and secular, lyrical (made sublime by Sandrine Piau) and orchestral, romantic in every way. Rinaldo Alessandrini is one of the leading figures in the international early music scene.

The cantatas of volume 19 can be relegated to three groups: Four works (BWV 72, 88, 129 and 193) belong to the third Leipzig series, lasting from 1725 to 1727; five (BWV 145, 159, 171, 174 and 188) belong to the group known as the Picander cycle of 1728-29, which was not completed or has not survived complete; two works (BWV 51 and 117) belong to the period after 1730, in which Bach composed new church cantatas only sporadically.
